Definitions
- the present devices and methods relate generally to medical devices and methods for filtering and/or collecting tissue, which has been cut or resected from various regions of a patient's body.
- Suction supplied by an external vacuum source is often used to evacuate tissue from the operative site.
- Medical devices which cut and evacuate tissue are used in a variety of procedures, including ear, nose, and throat surgery, gynecological surgery, spinal surgery, ophthalmic surgery, and many other applications. Depending on the procedure, the evacuated tissue may be collected for analysis.
- a fluid medium such as air, water, or a combination of air and water are frequently used to conduct resected tissue away from the operative site where it was resected.
- Flow through a tissue collection chamber may be reduced as tissue is collected in the chamber. This occurs when the tissue obstructs flow through the filter media.
- the reduction in flow through the filter and consequently through the cutting device may prolong the procedure by reducing the efficiency of the cutting device.
- the clogged filter may reduce the flow of suction available and result in increased clogging of the cutting device and/or limit the amount of tissue that can be collected or filtered.
- a filter for filtering and/or collecting tissue resected from a patient may include an inner chamber having a first end, a second end, and a wall.
- the wall may include one or more openings.
- the filter may include an outer chamber having a first end, a second end, a wall, an outlet port, an inlet port.
- An outer chamber lid may also be provided.
- the outer chamber may be configured to receive the inner chamber.
- the inner chamber is removably inserted in the outer chamber and the inner chamber is positioned within the outer chamber such that a gap is maintained between an outer surface of the wall of the inner chamber and an inner surface of the wall of the outer chamber.
- the gap may include a gap first portion and a gap second portion.
- the width of the gap first portion may be less than a width of the gap second portion.
- the filter may allow a fluid or fluid medium having resected tissue therein to flow through the inlet port into the inner chamber and at least partially through the openings in the wall of the inner chamber.
- the filter may remove resected tissue from the fluid medium by allowing the fluid medium to pass through the gap first portion, through the gap second portion and out of the outlet port, while the gap first portion inhibits or prevents the passage of resected tissue through the gap first portion and resected tissue is collected in the inner chamber.
- a method of filtering and/or collecting tissue resected from a patient may include one or more of the following steps.
- a fluid medium having resected tissue therein is passed into a filter.
- the filter may include an outer chamber having an outlet port, an inlet port, an outer chamber lid, and an inner chamber removably inserted in the outer chamber.
- the inner chamber may have a first end, a second end, and a wall.
- the wall may include one or more openings and the inner chamber may be positioned in the outer chamber such that a gap is maintained between an outer surface of the wall of the inner chamber and an inner surface of a wall of the outer chamber.
- the gap may include a gap first portion and a gap second portion.
- the fluid medium having resected tissue therein may be passed through the inlet port of the outer chamber, where the fluid medium and resected tissue impact the second end of the inner chamber, which is positioned adjacent to the outlet port of the outer chamber.
- the fluid medium having resected tissue therein is passed at least partially through the openings in the wall of the inner chamber. Resected tissue is removed from the fluid medium by allowing the fluid medium to pass through the gap first portion, through the gap second portion and then out of the outlet port, while the gap first portion inhibits or prevents the resected tissue from passing through the gap first portion.
- the resected tissue is collected in the inner chamber thereby filling the inner chamber with tissue from the second end of the inner chamber to the first end of the inner chamber while the fluid medium continues to flow out of the inner chamber and out of the outlet port until the filter is filled or substantially filled with tissue.
- FIG. 1 illustrates a variation of a filter showing the inner chamber suspended over the outer chamber.
- FIG. 2 illustrates a variation of a filter where the lid of the outer chamber is in a closed position over the opening of the outer chamber.
- FIG. 3A illustrates a cross sectional view along a vertical plane of the filter of FIG. 2 , where the inner chamber is positioned within the outer chamber and the lid of the outer chamber is in a closed position.
- FIG. 3B illustrates a cross sectional view through a horizontal plane of the filter of FIG. 2 , looking toward the outlet port fluid exit of the outer chamber.
- FIG. 4 illustrates a cross sectional view through a horizontal plane of the filter of FIG. 2 , looking toward the outlet port fluid exit of the outer chamber, including arrows depicting the fluid flow path through the filter.

- the outer chamber lid may be coupled to the outer chamber wall or body with a linkage or flexible member which acts as a hinge to allow the outer chamber lid to open and close over the opening at the first end of the outer chamber.
- the lid may close over the outer chamber opening and create or form a seal or closure with the outer chamber, e.g., over a first or second end or lip of the outer chamber, to prevent leakage.
- the lid may make or may not make contact with the first end of the inner chamber, when the inner chamber is positioned in the outer chamber.
- the lid may make contact with an end of the inner chamber when the inner chamber is positioned in the outer chamber, forming a seal or closure with the inner chamber and the outer chamber to prevent leakage.
- the flexible member may be an integrated flexible member.
- the inlet port and outlet port are configured to be connected to a conduit, tubing or other connector through which a fluid medium is conducted.
- the fluid medium may include resected tissue.
- a tubing or conduit may be coupled or connected to the inlet port by being positioned over the inlet port.
- a tubing or conduit may be coupled or connected to the outlet port by being positioned over the outlet port.
- a conduit, tubing or other connector may be coupled or connected to the inlet port and/or the outlet port by being inserted into the inlet port or outlet port or by forming other connections or being configured to accept a piece of tubing or conduit.
- a fluid medium with resected tissue may flow into and enter the filter through the inlet port, e.g., flowing from a connected conduit or tubing that conducts the fluid medium and/or resected tissue to flow into the filter, through the inlet port.
- the fluid medium may include a gas, liquid, or a combination thereof.
- the filter is designed to collect all or a portion of the resected tissue within the inner chamber before or as the fluid medium flows out of the outlet port.
- the inner chamber may be removably inserted or positioned in or within the outer chamber.
- the inner chamber may be positioned in the outer chamber such that a gap or space is maintained between an outer surface of the wall of the inner chamber and an inner surface of the wall of the outer chamber.
- the gap may have varying dimensions or a single uniform dimension.
- the gap may include a gap first portion and a gap second portion.
- the width of the gap first portion may differ from the width of the gap second portion.
- the width of the gap first portion may be less than the width of the gap second portion.
- the gap first portion may have a depth or length that is greater than or equal to its width.
- the width may refer, e.g., to the distance between the wall of the inner chamber and the wall of the outer chamber.
- one or more or several gaps or gap portions e.g., having varying widths or sizes, may be provided between the inner and outer chambers.
- a fluid medium carrying resected tissue may flow through an inlet port of the outer chamber or outer chamber lid and flow from the inlet port into the inner chamber.
- the fluid medium having resected tissue therein may then flow at least partially through the openings or slots in the wall of the inner chamber.
- the filter removes or separates resected tissue from the fluid medium by allowing the fluid medium to pass through the gap first portion and then through the gap second portion and ultimately out of the outlet port of the outer chamber.
- the gap first portion inhibits or prevents the resected tissue from passing through the gap first portion.
- the gap first portion has dimensions or a width which is sized to allow the fluid medium to pass through the gap first portion but to inhibit tissue from passing through the gap first portion.
- the dimensions or width of a gap or gap first portion may vary depending on the particular use of the device, e.g., depending on the type and size of the objects or tissue to be collected or filtered.
- the tissue that is inhibited from passing through the gap first portion is collected in the inner chamber.
- the collected tissue may be protruding out of the slots and/or it may be flush with the slots, yet still be held by the inner chamber.
- the tissue may be behind the slots in the inner chamber as well. The collected tissue remains held by the inner chamber, such that upon removal of the inner chamber from the outer chamber, the tissue can be removed from the filter with the inner chamber, and then emptied out of the inner chamber for testing, disposal or other use.
- the gap first portion may have a depth that is greater than its width. The greater depth creates a long passageway making it difficult for any resected tissue that may enter the gap first portion to navigate through the entire length or depth of the gap first portion. If any resected tissue passes through the entire gap first portion, the wider gap second portion allows the piece of resected tissue to pass from the gap second portion to the outlet port and to exit the filter, thereby preventing or reducing tissue clogging in the gap or space or gap second portion between the inner chamber and the outer chamber to avoid, reduce or prevent a reduction in fluid flow rate.
- the outer chamber wall may have a varying wall thickness around its circumference or around at least a portion of its circumference to provide varying space between the inner chamber and the outer chamber. For example, this may provide the gap first portion with a width that is less than the width of the gap second portion.
- the inner chamber wall may have a varying wall thickness.
- the varying wall thicknesses of the inner and/or outer chamber walls may create one or more gaps or spaces of varying size or width between the chambers.
- the varying space or gap between the inner chamber and outer chamber may inhibit or prevent the passage of objects larger than the gap or space while allowing the fluid medium to pass through the smaller gaps or spaces and then to flow freely through the larger gaps or spaces.
- This provides a path for the fluid to flow through a slot or opening in the inner chamber, through the narrow space (e.g., the gap first portion) between the walls of the inner chamber and outer chamber, and into the wider space (e.g., the gap second portion which may be wider than the gap first portion) between the inner chamber and outer chamber.
- the spacing between the surfaces of the inner chamber or component and the outer chamber or component may be adequate to allow a fluid medium to pass but restricts or inhibits the flow of tissue thereby collecting the tissue in the tissue collection chamber.
- the gap may have a constant width, such that there is no varying width between the gap first portion and the gap second portion, e.g., the gap first portion may have a width that is equal to the width of the gap second portion.
- a gap may have a width that is less than, equal to or greater than its length or depth.
- the inner chamber may be positioned into the outer chamber such that the wall of the outer chamber is spaced away from the wall of the inner chamber in a controlled manner to maintain consistent spacing between the inner chamber and the outer chamber.
- the space or gap between the walls of the inner and outer chambers may be sized not to allow tissue larger than the size or width of the space or gap (i.e., the distance between the outer surface of the wall of the inner chamber and the inner surface of the wall of the outer chamber) to pass into the outer chamber or out of the outlet port.
- the gap first portion may be about 0.020 of an inch in width and the gap second portion may be larger than 0.020 of an inch in width.
- the filter may include one or more components or features configured to position the inner chamber within the outer chamber such that a consistent spacing is maintained between the outer surface of the inner chamber wall and the inner surface of the outer chamber wall.
- the outer chamber or the inner chamber may include one or more components or features to properly position the inner chamber within the outer chamber such that a consistent and stable spacing is provided and maintained between the outer surface of the inner chamber wall and the inner surface of the outer chamber wall.
- the various filter designs described herein can filter tissue while minimizing flow losses as the tissue is collected.
- the filters may also provide easy access to collected tissue, where the inner chamber may be removed in order to empty or sample the tissue collected therein, while the filter and outer chamber remains connected or coupled to a tissue cutting device. Removal of tissue may be assisted by slots which or long or vertically arranged and/or sloped, where tissue slides down the slots and out of the inner chamber end opening during emptying without being held up or restricted by the slots.
- the various filter designs described herein may have rigid or non-rigid components which are completely or at least partially rigid or non-rigid.
- the outer chamber may be rigid, where the inner chamber is non-rigid allowing for some flexibility as it is inserted or removed from the outer chamber.
- the inner and outer chamber may both be rigid, both be non-rigid, one can be rigid while the other is non-rigid, and/or the outer chamber lid may be non-rigid or rigid.
- the components of the filter may be transparent or opaque or a combination thereof.
- the various filters or tissue collection devices described herein may be used with a variety of medical instruments, including, e.g., various tissue cutting or resection devices or various aspirators, to assist with the collection of tissue removed or resected from various anatomical regions of a patient.
- the tissue cutting or resection devices may utilize vacuum suction for tissue removal and/or may be powered by a variety of power sources, including, e.g., vacuum power, electrical power, battery power, gas power, compressed or pressurized gas power.
- the various filters or tissue collection devises described herein may be used with any of the medical instruments described in US Pub. App. 2013/0211438; US Pub. App. 2013/0046199; or US Pub. App. 2013/0218186.
- the filter may be positioned on its side or in a horizontal position or orientation.
- the tissue and fluid medium may enter the filter and the tissue may fill the inner chamber of the filter from one end, e.g., a second end, adjacent the outlet port of the outer chamber, to the other end, e.g., a first end, adjacent the inlet port of the outer chamber, regardless of the orientation of the filter.
- the suction pulled through the device may cause the fluid medium and/or resected tissue to enter the filter and impact the second end of the inner chamber first, filling the inner chamber from a second end of the inner chamber to the first end of the inner chamber.
- the filter may be used in any orientation, e.g., horizontal or vertical relative to the patient or the instrument used to resect, cut or remove tissue or other material

- FIGS. 5A-5C illustrate the cross sectional views of a variation of a filter 2 at different stages of tissue collection.
- Arrows A (with dashed lines representing a transparent view of fluid flow between the inner and outer chambers) show the fluid flow path from the inner chamber, through the gap first portion 41 and gap second portion 42 between the inner chamber 10 and outer chamber 20 and out of the outlet port 21 , as tissue T (which is represented generally by the spheres T in the drawings) is collected in the inner chamber 10 .
- the fluid medium carrying resected tissue enters the inner chamber 10 through the inlet port 27 , and impacts the second end 14 of the inner chamber 10 .
- the fluid medium with resected tissue then flows through or into the slots 12 and to the gap first portion 41 .
- the fluid medium with resected tissue arrives at the gap first portion 41 , the fluid continues to flow into the gap first portion 41 .
- objects and tissue larger than the gap first portion 41 are stopped or inhibited from passing through the gap first portion 41 (i.e., they are inhibited or blocked by the size or width restrictions of the first gap portion or space between the outer surface of the wall of the inner chamber 10 and the inner surface of the wall of the outer chamber 20 ).
- the fluid flows or passes through the gap first portion 41 and then passes through the gap second portion 42 .
- the fluid then flows from the gap second portion 42 to the outlet port 21 and out of the filter 2 into a tube or other conduit coupled to the filter 2 , where the fluid is conducted or taken away from the filter 2 .
- the filter can filter and collect tissue while minimizing or substantially reducing any restriction or reduction in flow or flow rate as the inner chamber or filter fills with tissue.
- the fluid flow rate through the filter may maintain constant or substantially constant as the tissue fills the inner chamber, or it may drop initially, when for example openings at the second end of the inner chamber (in variations having such openings) are blocked with tissue, and then remain constant until the inner chamber is completely or substantially filled or the one or more slots are fully, completely or substantially blocked.
- a width of the gap first portion may be consistent around the entire circumference of the filter and a width of the gap second portion may be consistent around the entire circumference of the filter.
- a tissue collection device may include one or more spaces between an inner chamber wall and an outer chamber wall of the device, which inhibit the passage of tissue while allowing the passage of fluid.
- the spacing between the inner chamber wall and outer chamber wall may be varied to provide a short path for the fluid to travel through a narrow passageway and then into a larger, less restrictive volume.
- the fluid medium generally flows through or between slots in the inner chamber, through a small or narrow space between the inner chamber and outer chamber and into a large, less restrictive space between the inner chamber and the outer chamber before then flowing to the exit port and out of the device or filter. Filter of the tissue or removal of the tissue from the fluid medium is performed by the one or more spaces or gaps between two components, i.e., the spaces or gaps between the inner chamber and the outer chamber of the device or filter.
- a medical device for collecting tissue includes an inner chamber and an outer chamber wherein fluid medium is capable of passing through narrow passageways between the walls of the inner chamber and the outer chamber while inhibiting the passage of tissue through said passageways.
- the space between the inner chamber and outer chamber wall may vary in size.
- the surface of the inner chamber adjacent to the exit port on the outer chamber has openings of an appropriate size to inhibit the passage of objects through the openings while allowing fluid to pass through the openings.
- the inner chamber may be removed from the outer chamber.
- the collected objects or tissue may be removed from the medical device and remain in the inner chamber when the inner chamber is removed from the outer chamber.
- the space between the inner chamber and outer chamber may be controlled by features on the inner chamber.
- the space between the inner chamber and outer chamber may be controlled by features on the outer chamber.
- the various filters and tissue collection devices described herein allow for the tissue that is collected within the inner chamber to be easily accessed and facilitate recovery of collected tissue both intra-operatively and post-operatively.
- the filters described herein facilitate pathological analysis and may allow for the removal of tissue intra-operatively, e.g., to keep tissue from different locations within or on the body isolated from one another.
- Methods of filtering and/or collecting tissue resected from a patient may include one or more of the following steps.
- a fluid medium having resected tissue therein may be passed into a filter.
- the filter may include an outer chamber having an outlet port and an outer chamber lid having an inlet port, and an inner chamber removably inserted in the outer chamber.
- the inlet and outlet ports may be reversed, with the outlet port being on the lid and the inlet port being at another end of the outer chamber.
- the inner chamber may include a first end, a second end, and a wall extending from the first end to the second end.
- the wall may include one or more openings and the inner chamber may be positioned in the outer chamber such that a gap is maintained between an outer surface of the wall of the inner chamber and an inner surface of a wall of the outer chamber.
- the gap may include a gap first portion and a gap second portion.
- the fluid medium having resected tissue therein is passed through the inlet port of the outer chamber or outer chamber lid.
- the fluid medium and resected tissue enter the inner chamber and impact the second end of the inner chamber, which is positioned adjacent to the outlet port of the outer chamber.
- the fluid medium having resected tissue therein is at least partially passed through the openings in the wall of the inner chamber.
- the resected tissue is removed or separated from the fluid medium by allowing the fluid medium to pass through the gap first portion, through the gap second portion and then out of the outlet port, while the gap first portion inhibits, blocks or prevents resected tissue from passing through the gap first portion.
- the resected tissue is collected in the inner chamber by filling the inner chamber with tissue from the second end of the inner chamber (e.g., the end opposite the inlet port) to the first end of the inner chamber (e.g., the end adjacent the inlet port) while the fluid medium continues to flow out of the inner chamber and out of the outlet port, e.g., until the inner chamber is full or substantially full with tissue.
- the gap first portion may have a width which is sized to allow the fluid medium to pass through the gap first portion and to inhibit tissue having a size greater than the gap first portion or greater than the width of the gap first portion from passing through the gap first portion.
- the tissue that is inhibited from passing through the gap first portion may be collected in the inner chamber.
- the filter may remove resected tissue from the fluid medium by allowing the fluid medium to pass through the gap first portion, from the gap first portion through the gap second portion, and from the gap second portion out of the outlet port.
- the gap first portion may inhibit or restrict resected tissue from passing through the gap first portion.
- the outer chamber wall may have a varying thickness around its circumference to provide the gap first portion with a width that is less than the width of the gap second portion.
- the second end of the inner chamber which is positioned adjacent the outlet port of the outer chamber may include a plurality of openings that allow fluid to pass through the openings, while inhibiting the passage of tissue, thereby trapping tissue in the inner chamber.
- a consistent spacing may be maintained between the outer surface of the inner chamber wall and the inner surface of the outer chamber wall.
- the outer chamber may include one or more components configured to position the inner chamber within the outer chamber such that a consistent spacing is maintained between the outer surface of the inner chamber wall and the inner surface of the outer chamber wall.
- the one or more openings in the wall of the inner chamber may be in the form of a slot, where the slot extends from a first end of the inner chamber wall to the second end of the inner chamber wall.
- the one or more openings in the wall of the inner chamber may have a width and a length, where the length is greater than the width.
- the wall of the inner chamber may include a plurality of slots positioned around the circumference of the inner chamber, wherein each slot is separated from an adjacent slot by at least a portion of the wall.
- the inlet port and outlet port of the filter may be configured for connection to a first tubing and second tubing through which the fluid medium is conducted.
- the tubing may be coupled to the filter by being positioned over or inserted in the inlet port or the outlet port.
- fluid medium and/or tissue flows through the inlet port and into the inner chamber of a filter or tissue collection device.
- the fluid medium and/or tissue starts filling the inner chamber and slots from a second end of the inner chamber, that is adjacent to the outlet port of the outer chamber, toward a first end of the inner chamber, that is adjacent to the inlet port of the outer chamber.
- the fluid medium and/or tissue flows through the slots of the inner chamber.
- the fluid medium flows into the gap first portion, while tissue larger than the width of the gap first portion is inhibited and trapped in the inner chamber. Fluid flows from the gap first portion into the gap second portion, which has a greater width than the gap first portion.
- the gap second portion leads to the outlet port so that the fluid flows from the gap second portion to the outlet port and fluid flows out of outlet port, thereby exiting the filter.
- one or more gaps or gap portions having varying sizes or widths may be provided, e.g., a series of successive gaps having varying sizes, widths or dimensions may be provided to inhibit or prevent the passage of tissue between the inner and outer chambers and/or out of the filter.
- filtration may be performed by the gap or space maintained between two components, i.e., between the inner chamber and an outer chamber of the filter, in contrast to filtering solely through small molded holes or slots in a single component.
- the inner chamber has one or more openings in its second end in addition to the openings or slots in the wall of the inner chamber, some filtration may take place via the openings in the second end of the inner chamber as well.
- the gap first portion may be longer or deeper than it is wide, such that the fluid medium has to go through a long passageway or hallway rather than a short orifice.
- a long passageway or hallway configuration of a gap makes it more difficult for tissue that does pass into the gap first portion, e.g., smaller tissue, to navigate or pass through the full length of the gap first portion. If the tissue does get through the gap first portion, it would then enter the gap second portion which is wider than the gap first portion, and allows the tissue to more easily pass through to the outlet port and to exit the filter to prevent clogging of the gaps and the filter by any tissue that inadvertently slips or passes through the gap first portion.
- One or more gaps may provide a tortuous pathway to inhibit or prevent the passage of tissue out of the filter.
- the inner chamber may have one or more slots in the wall of the inner chamber, and the slots may be in fluid communication with the gap.
- the fluid medium and/or tissue enters the inner chamber and as the slots get loaded with tissue at the second end of the inner chamber, which sits adjacent the outlet port, the first end of the slot (or unfilled or unblocked portion of the slot) still has a fluid flow pathway to allow fluid to pass into the gap while tissue is being collected. Therefore, tissue is filtered from the second end of the inner chamber to the first end of the inner chamber and as a result, the gap doesn't get completely blocked until the filter is nearly full or full, thereby minimizing or eliminating any reduction in flow rate as tissue is collected and starts to block or fill the slots. The filter is not loaded or completely blocked until it is full or nearly full with tissue.
- the filter or tissue collection chambers described herein are intended to cause air or other fluid to flow into the inner chamber and through the gap, i.e., through the gap first portion and then into the gap second portion between the inner and outer chambers, and then out of the exit port.
- This airflow or fluid flow minimizes the restriction to flow while the filter fills with tissue.
- tissue momentum causes the tissue to impact the second end of the filter (adjacent the outlet port) and to stay there rather than flow to the first end of the inner chamber (adjacent the inlet port).
- the filter chamber is filled from the second end (outlet port end) to the first end (inlet port end) regardless of the orientation of the filter.
- the filter is less likely to slow down as tissue is collected and the filter starts to get loaded with tissue.
- the tissue can easily be removed intra-operatively by removing the inner chamber from the outer chamber and emptying the tissue contents.
- the filter is easy to manufacture because small filtration features don't have to be created in the plastic tooling.
